Specification of Letters Patent.

Patented Apr. 9, 1912.

Application filed August 31, 1911. Serial No. 647,038.

One object of my invention is to construct a conveyer of the type which will carry fiat material and which will allow for the free passage of air to the material;

A further object of the invention is to make a conveyer in such a manner that it can be economically manufactured and readily assembled, and which will be light and strong.

In the accompanying drawings, Figure 1, is a perspective view of a portion of my improved conveyer; Fig. 2, is a transverse sectional view on the line aa, Fig. 3; Fig. 3, is a plan view of a portion of the conveyer; Fig. 4, is a longitudinal sectional view on the line bb, Fig. 3; Fig. 5, is an enlarged longitudinal sectional view illustrating a detail of the invention; Fig. 6, is an enlarged transverse sectional View on the line 0-0, Fig. 5; Fig. 7, is a detached perspective view of one of the longitudinal bars; and Fig. 8, is a perspective of a modification of the transverse members.

While my improved conveyer can be used for conveying materials 1n general, it is es pecially adapted for use in machines for type usually passes through a suitable chamber in the presence of either heated or cooled air according to the material acted upon.

.One of the essential features of the invention is to make the conveyer fiat on the carrying surface and this is particularly advantageous in carrying veneers and paper stock in sheets.

The conveyer is made of a series of longitudinal bars 1 bent at each endto form hooks 2, which engage the transverse sup.- porting members 3. These hooked bars are spaced a given distance apart according to the material to be conveyed, as clearly shown in Figs. 1 and 3. The transverse members 3 are carried in the present instance by side chains 4:, as indicated in Fig. 2. These side chains may be of any suitable type made up of links 5 and 6, Fig. 4. The links 5' are specially shaped and are perforated to receive the ends 7 of the transverse members 3 while the links 6 are planelinks connecting the links 5. The transverse members 3 are inserted in their respective links and are made of sheet metal bent into the form illustrated in Figs. 5 and 6. The portion 8 is in the form of a tube, and the stiffening web 9 is made in two parts flared as shown in Figs. 1 and 5, so as to stiffen the member laterally as well as longitudinally. The web is perforated at intervals directly below the tubular portion 8, as shown at 11. These perforations, in the present instance, are in the form of slots. The hooked ends of the bar 1 pass around the tubular portion 8 and their ends extend through the slots 11. By this construction the bars are held against vertical movement and are held a given distance apart, and yet are free to move longitudinally to a limited extent to accommodate themselves to the movement of the conveyer; especially in passing around the guides at the end of the run.

It will be understood that the longitudinal bars can be spaced at any distance desired and in some cases the bars may not be hooked in every slot in the transverse member when it is desired to make a conveyer in which the bars are located a distance apart, but, as a general rule, the punching of the slots in the cross member defines the spacing of the longitudinal bars.

I preferably make the cross member with the ends flaring as shown in the main figures, of the drawing so as to give the said cross member the lateral strength and stiffness desired, although in some instances, the member may be made as shown in Fig. 8 and the edge of one plate 10 turned up to overlap the other plate. In the present instance, the chains have rollers 12, which travel on guide rails 13 and may be held vertically by a guard rail, while traversing the upper run and at the end of the run the chains pass around the wheels or drums 14:. In some instances, where the material is to be held onto the carrying run of the conveyer two conveyers may be placed in such position that the lower run of one conveyer *will retain the material, such as a veneer, on the carrying run of the conveyer below it. Dif

ferent mechanism may be used for imparting motion to the conveyers and the conveyers may be located in any suitable compartments according to the treatment to which the material is to be subjected.

I claim:

1. The combination in a conveyer, of two side chains, a series of transverse supporting members extending from one chain to the other and spaced a given distance apart by the chains, said supporting members having openings therein, with a series of longitudinal carrying members having elongated hooks at each end, said hooks extending around a portion of the transverse members and through openings therein.

2. The combination in a conveyer of a series of transverse supporting members each having a rounded upper sect-ion and a perforated web section; with a series of rods bent at each end to form hooks; the rods resting upon the transverse members and the hooked ends extending through the perforated web section.

3. The combination in a conveyer, of a se ries of transverse members having perforations, with hooked longitudinal members, carried by the transverse members, the hooks extending through the perforations, the lower portions of the transverse members being flared for the purpose of stifi'ening said member.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
